Dual Cold
In this mode, the air handler supplies both ducts with cold air. If the dual supply sequence is
configured for series operation, the cold duct will supply air until it reaches its maximum. If
additional cooling is necessary, the hot duct will begin to supply air. If the dual supply sequence is
configured for parallel operation, the flow setpoints for both ducts will increase at the same time.

Dual Hot
In this mode, the air handler supplies both ducts with hot air. If the dual supply sequence is
configured for series operation, the hot duct will supply air until it reaches its maximum. If additional
heating is necessary, the cold duct will begin to supply air. If the dual supply sequence is configured
for parallel operation, the flow setpoints for both ducts will increase at the same time
